US professor said that the space expansion of earthlings will lead to the spread of totalitarianism

Political scientist Daniel Dodney believes that the foundation for future space conflicts is being laid on Earth today.

Space exploration is one of the main priorities for humanity in the 21st century. But not everyone agrees that the exit of our civilization beyond the boundaries of the globe will do more good than harm. For example, Daniel Dodney, professor of political science at Johns Hopkins University in the United States, believes that we should not attempt space expansion at all.

Dewdney is confident that the emergence of new habitats for people, in addition to the Earth, will lead to the emergence of interplanetary totalitarian empires. And if mankind somehow manages to master at least a few planets of the solar system, then nuclear weapons will become the “gold standard” in all wars (which, according to the professor, will not stop).

Although many colleagues consider Daniel’s arguments too pessimistic, the political scientist himself generally believes that people should abandon the exploration of outer space and search for a new home. 

“The large-scale expansion of human activity into space <…> must be included in the growing list of catastrophic existential threats to humanity,” Dodni insists.

No matter how gloomy the views of the American political scientist may look, they have certain grounds. So, in 2019, the United States announced the creation of a new type of its Armed Forces – space: they are “designed to protect the interests of the United States in space, deter aggression at long distances and conduct operational and consistent space operations.”

Other countries followed the American example: France, Canada and Japan announced their intentions to create similar troops. According to Dodnya, all this testifies to laying the foundation for future “near-earth conflicts.” According to his forecasts, space special forces will one day be able to control asteroids and comets to destroy settlements on rival planets or change the climate there, causing total extinction.

At the same time, the political scientist notes that he has nothing against “using space in ways that will benefit the Earth.” However, he doubts that this is possible.

Astronomers at Australia’s ASKAP radio telescope complex have reported that they have discovered strange circles of radio emission in space. According to their characteristics, they do not fit into any of the known types of objects. 

The research results have been prepared for publication in the journal Publications of the Astronomical Society of Australia and are available at arXiv.org.

ORC (Odd Radio Circles) – “strange radio circles” detected by the ASKAP telescope

In late 2019, the Australian Square Kilometer Array Pathfinder (ASKAP) radio telescope complex – one of the most sensitive in the world – detected three strange circular objects while collecting data to compile an Evolutionary Map of the Universe (EMU).

The circles of radio emission hung in the sky like cosmic smoke rings. Astronomers have called them “Odd Radio Circles” or “Orcs” (ORC).

“A couple of years ago I predicted that this exploration of the unknown would lead to unexpected discoveries, which I called WTF. But none of us expected to find something so unexpected and so quickly, ” writes the author of the new discovery, Professor of Western Sydney University Ray Norris.

At first, scientists thought that these were artifacts caused by errors in software processing, but soon the reality of the Orcs was confirmed by other radio telescopes. Astronomers have never found anything like this before. Objects are only visible in radio waves and not detectable in X-ray, optical or infrared ranges.

Researchers from the EMU project examined the entire volume of ASKAP data and found many more radio circles. The authors estimate that there are about a thousand ORCs in the sky.

So far, scientists only make assumptions about the possible origin of mysterious objects. It is not known even at what distance from the Earth they are – in our Galaxy or far in the Universe. Accordingly, their size is also unknown – preliminary analysis showed that the diameter of the found SRCs is several light years if they are in our galaxy, and several million light years if they are in deep space.

“When analyzing the position of the SRC with the help of optical telescopes, we see nothing. The radio emission rings are likely caused by clouds of electrons, but why can’t we see anything at the visible wavelengths of light? We don’t yet know the answer to this, but finding such a puzzle is every astronomer’s dream,” Ray Norris, professor at the University of Western Sydney explains.

In their article, the authors list what exactly these strange radio circles cannot be. According to the researchers, these are not supernova remnants – they are located far from most of the stars in the Milky Way, and there are too many of them.

These are not regions of star formation, as there are no galaxies nearby.

It is unlikely that these are the “petals” of radio galaxies, created by jets of electrons escaping from the vicinity of a supermassive black hole – orcs are distinctly round, in contrast to the entangled clouds of radio galaxies.

They are also not like Einstein’s rings , in which radio waves from a distant galaxy bend into a circle under the action of the gravitational field of a cluster of galaxies – the radio circles are too symmetric and they do not have a cluster in the center.

Scientists are now looking around the world for radio telescopes that could continue observing strange radio circles in order to ultimately find an answer to the question of their origin.

“It’s not an easy job because the signals from the ORC are very weak and hard to find. Our team is brainstorming, hoping for a eureka moment when one of us, or perhaps someone else, suddenly has a flash of insight that will solve the riddle, “said the first author of the article, Ray Norris in an interview with The Conversation.” This is an exciting time for us. Most astronomical research is aimed at refining our knowledge of the Universe or testing theories. Very rarely we have to stumble upon a new type of object that no one has seen before, and try to figure out what it is. “

As a working version, scientists suggest that the strange radio circles are shock waves from explosions in distant galaxies, fast radio bursts, or collisions of a neutron star and a black hole.

In 2021, the Moon will host a car race driven by schoolchildren

In 2021, the Moon will host a car race driven by schoolchildren 94
MAPP project

In 2021, a remote controlled rover race will take place on the lunar surface. At the same time, the development of these cars will be carried out by the famous auto designer Frank Stephenson, who worked with BMW, Ferrari and other whales of the automotive business, and … schoolchildren. Such an amazing statement was made by representatives of the Moon Mark project.

On October 11, 2021, the launch of the Nova-C device, developed by Intuitive Machines, is planned. This probe is slated to land softly on the surface of Selene in the Ocean of Storms.

If successful, it will be the first soft-landing probe designed and manufactured by a private company (not with private money, though).

Nova-C is capable of delivering up to one hundred kilograms of payload to the moon. Most of it is NASA’s scientific instruments, which funded the project. By the way, NASA allocated $ 77 million for the creation and launch of the spacecraft . However, the contract stipulates a certain payload limit, which Intuitive Machines has the right to spend at its discretion.

And eight kilograms of this limit will be allocated to … racing rovers from the Moon Mark company. Each vehicle will weigh 2.5 kilograms, and another three kilograms will be a system for deploying them on the surface of Selena.

This is a very extravagant decision (although how is it worse than sending a car on an interplanetary trip by Elon Musk ?).

Recall that over the past 40 years there have been only five attempts at soft landing on the moon. Of these, two ( Israeli and Indian ) ended in failure. And now it turns out that 8% of the space on the device flying to Selena (and the cost of this 8%, based on the project budget, will amount to more than $ 6 million) will be spent on entertainment for children.

In this place, any scientist who for decades dreamed of delivering his device to the moon for certain scientific research could start banging his head against the wall.

But the project developers have their own reasons. The race will attract the attention of society to space exploration, and above all of the younger generation. But these are future astronomers, engineers, entrepreneurs, and also voters and even politicians. If today’s children light up with the dream of exploring the Universe, and then carry it into their hearts into their adult life, then this $ 6,000,000 (by the way, not such a large amount by the standards of modern astronautics) will turn out not to be a reckless waste, but a very profitable investment in the future of humanity.

What will this project look like in practice? The lunar surface races will be the main prize of the Moon Mark’s Mission 1 competition, which will feature six teams of high school students. Schoolchildren will compete in drone races, space mission design and other fun things.

The two winning teams will receive the right to operate the racing moon rovers (from Earth, of course). But first, they will take part in their development. The chassis, controls and other important systems will of course be designed by specialists.

It is known for certain that the schoolchildren will work out the body design (here the famous Frank Stevenson will help them). This is also not an easy task. After all, the body must protect the device from damage in accidents and save it from the ubiquitous moon dust. In addition, when designing it, the mass distribution and many other technical parameters must be taken into account.

The prototype of the racing lunar rovers will be the MAPP project from the Lunar Outpost company (it is covered in more detail in the video below). True, the concept will have to be finalized, because the MAPP devices weigh 10 kilograms and move at a speed of only 360 meters per hour, which is by no means dizzying.

Note that the actual pace of the races is a separate issue. The speed of future rovers has not yet been announced. However, the radio signal takes 1.3 seconds to reach the moon and the same time to return. It is unlikely that this way you can control something really fast in real time.

The route of future races is also yet to be laid.

“There is a trail that designs Hermann Tilke, who designed all the latest track,” Formula 1 “around the world” – says Stevenson material New Atlas.

Of course, the path will not be marked in any way on the lunar surface. Perhaps the route will be shown as a line on the screens where young operators will follow the movement of their vehicles.

In any case, the feast of technical thought will not be long. The Nova-C device is not equipped with heaters, which means that the life of its entire payload is one lunar day (about two Earth weeks).

In December, Earth’s inhabitants will be able to see a rare cosmic phenomenon

In December, Earth's inhabitants will be able to see a rare cosmic phenomenon 96

At the end of the year, astronomers expect to see a rare cosmic phenomenon dubbed the “Christmas star” in the sky. It will be caused by the fact that Saturn and Jupiter come close to each other at a minimum distance and almost collide to become one super-bright point of light.

These two planets became one straight line in the solar system a few weeks ago, but at the end of December they will be on it for observers from Earth. This will happen on December 21, 2020, on the day of the winter solstice, when the daylight hours are the shortest and the night is the longest. Jupiter and Saturn will look like a “double planet” for the first time since the Middle Ages, Forbes writes.

“The conjunctions of the two planets are extremely rare, but this particular conjunction is especially rare because the planets will be very close to each other,” Patrick Hartigan, astronomer at Rice University, USA said. “In order to observe a closer conjunction of these planets in the night sky, we would have to return on March 4, 1226.”

It is noted that the unusual celestial phenomenon can be observed from anywhere on the planet. The main thing is that the sky is clear. The “Christmas Star” can be seen in the western sky about an hour after sunset when viewed from the northern hemisphere.

“On the evening of their closest approach, December 21, they will appear as a twin planet, separated by less than 1/5 the diameter of the full moon,” Hartigan said. “For most amateur astronomers looking at the night sky through a telescope, both planets and several of their largest satellites will be in the same field of view this evening.”

Those who want to see Jupiter and Saturn converge in the sky as close, but will be higher above the horizon, will have to wait until March 15, 2080, Hartigan said. After that, a similar configuration for this planetary pair will not be observed until 2400.

Astronomers are already preparing equipment to analyze in detail the upcoming event. Everything is very serious, because the second such rapprochement between Jupiter and Saturn cannot be expected.

Of course, there will not be a collision of planets. You just get the impression that something terrible is about to happen in the solar system. Astronomers have assured that there is no reason to worry.

Is the “Christmas Star” an omen of things to come? Mark your calendars!
